Product Disassembly Introduction to Engineering Design © 2012 Project Lead The Way, Inc.

Product Disassembly Disassembly or teardown of a product is a major step in the reverse engineering process It uncovers the principles behind how a product works It is always fun to tear apart a product, but nothing will be accomplished if data is not collected during the process To gather this data, we will use a Product Disassembly Chart

Answer the Following Questions Presentation Name Course Name Unit # – Lesson #.# – Lesson Name Answer the Following Questions How do the parts interact? What are the good and bad features of the product? Form Function What has caused the product to succeed or fail? Are the materials appropriate? What manufacturing process was used? What is the estimated cost of the product?

Why Disassemble a Product? To identify components and interaction of components To determine strength and weaknesses of parts To understand the operation To develop (computer) documentation

Initial Product Selection A product is selected for RE The product can range from simple (child’s toy) to complex (fishing reel)

Suggested Supplies for Disassembly Small drill Calipers Screwdriver set Socket set Wrenches Wire cutters Needle nose and regular pliers Radius gauge Hand saw / miter box and back saw Scale Protractor Handout – Product Teardown Chart Hand tool to compress springs DESTRUCTIVELY DISASSEMBLE YOUR PRODUCT ONLY IF YOU’RE SURE IT’S OK TO DO SO !!!

Product Disassembly and Documentation Procedure Disassemble the product Create pictorial sketches to describe the operation Carefully observe and measure each part Record your finding on the Product Disassembly Chart Create an annotated sketch of each part Compare your hypothesis for operation to the actual operation of the part Create 3D solid models for each part Document your findings
